Atherigona albistyla Deeming, 1971: 164, figs 81, 82; Deeming 1979: 40, figs 23–25; Deeming and Overman 1987: 117; Dike 2003: 219 (distribution); Muller and Mostovski 2018: 346, fig. 32; Deeming and Kirk-Spriggs 2024: 505.

Material examined.

Angola • 1 ♂; Bié, Camacupa 8 km ENE Camacupa, 12°0'45.70"S, 17°32'59.17"E, 03 Nov. 2022, T. A. Bellingan leg., by hand; AMGS -ENT 101806 .

Remarks.

Both Deeming (1971: 141) and Dike (1989: 557) have key couplets, 49 ’ and 53 ’ respectively, dealing with A. albistyla that have similar couplets stating erroneously that “ at least fore tibia largely infuscate, ” whereas the tibia of A. albistyla is only somewhat infuscated on the apical third. Additionally, Muller and Mostovski (2018: 345) mistakenly refer to the trifoliate process in couplets 21 and 21 ’ as “ Trifoliate process bilobate, never with a distinct bifurcation ” and “ Trifoliate process with either a deep or shallow bifurcation, ” respectively, but actually refer to the hypopygial prominence. These corrections are provided to allow future users to more easily use those keys. Deeming (1971: fig. 82) and Muller and Mostovski (2018: fig. 32) only figure the posterior view of the hypopygial prominence of A. albistyla . We now also include the lateral view of the hypopygial prominence, as it is quite distinctive in that each process apically widens with anterior and posterior sub-processes not mentioned in the original description. It should also be noted that the trifoliate processes figured by Deeming (1971: fig. 81), Dike (1989: fig. 77), and Muller and Mostovski (2018: fig. 32) end more pointed apically compared to the Angolan specimen that has the apex more rounded.
